Yatta! Saturday night =”Heroes” marathon

In case you need to catch up, NBC is airing the three most recent episodes of “Heroes” from 8 to 11 p.m. Saturday on KING/5: “Unexpected,” (the one where Peter figures out what being a power sponge means) “Company Man,” (H.R.G.’s backstory), and “Parasite” (where Sylar confronts Peter).

And as if you had any doubts, the latest episode “.07″ (9 p.m. Monday, KING/5) is worth the wait. I’ll leave the meat of the action a mystery so as not to spoil but in general….

–The whole phenomenon of superbeings has been going on longer than any of the current players thinks. And there are more experienced players in this game.

–This episode also connects the dots in some very surprising ways. Some alignments are quite surprising.

–The explosion they’re trying to stop? It’s only the beginning of something bigger. (Obviously.) This is the first episode where we get a clue as to how extensive those plans might be.

–Lastly, Mohinder Suresh might end up disappointing us in a big, big way by the end of this season.
